| 中文摘要: |
| 在“双碳”目标约束下，钢铁行业绿色转型亟须从总量控制转向效率提升。基于中国钢铁行业数据，本文采用全局非径向方向性距离函数（GNDDF）与全局Malmquist-Luenberger（GML）指数测度绿色全要素生产率（GTFP），并将其增长深度分解为三条路径：投入节约、期望产出扩张与非期望产出减排，从“源泉结构”视角解析绿色增长动力机制。在此基础上，构建“技术进步—分解路径—制度环境”分析框架，实证检验技术进步主导效应及环境规制与技术创新的协同机制。研究发现：①钢铁行业GTFP年均增长6.1%，技术进步贡献率达89.3%，是绿色增长的决定性驱动力；②GTFP呈现“产出扩张—投入节约—减排强化”的三重驱动结构，其中期望产出扩张贡献最大；③环境规制与技术创新不仅显著促进减排贡献，且存在正向协同效应；④“双碳”目标期叠加强规制与高政府支持的政策组合最有利于技术进步效率提升。研究表明，钢铁行业绿色转型正由“末端约束”向“内生效率驱动”阶段跃迁。本文突破传统TC/EC二分框架，提出GTFP三源泉分解方法，揭示技术进步作用的结构性路径，并识别规制与创新的协同机制，为精准化绿色政策设计提供实证依据。 |

| Under the constraints of the “dual-carbon” targets, the green transformation of the steel industry urgently needs to shift from total quantity control to efficiency enhancement. Based on China’s steel industry data, this study employs the Global Non-radial Directional Distance Function (GNDDF) and the Global Malmquist–Luenberger (GML) index to measure green total factor productivity (GTFP), and deeply decomposes its growth into three pathways: input saving, desirable output expansion, and undesirable output reduction, thereby analyzing the driving mechanism of green growth from the perspective of “source structure”. On this basis, an integrated analytical framework of “technological progress—decomposition pathways—institutional environment” is constructed to empirically test the dominant role of technological progress and the synergistic mechanisms of environmental regulation and technological innovation. The findings reveal that:① The average annual growth rate of GTFP in the steel industry is 6.1%, with technological progress contributing 89.3%, confirming it as the decisive driver of green growth;② A triple-driver structure is observed, led by output expansion, followed by input saving and emission reduction, among which expected output expansion contributes the most; ③ Environmental regulation and technological innovation not only independently promote emission reduction but also exhibit significant synergistic effects, demonstrating a virtuous cycle between regulation and innovation;④ Policy combinations featuring stringent regulation and strong government support during the dual-carbon period most effectively enhance technological progress. The study indicates that the green transformation of the steel industry is transitioning from the “end-of-pipe constraint” stage to the “endogenous efficiency-driven” stage. This study advances beyond the traditional TC/EC framework, proposing a three-path decomposition method, reveals the structural pathways of technological progress, and identifies the synergy between regulation and innovation, providing empirical evidence for precision-oriented green policy design. |
